An incredibly hot one-piece bat, B21-HOT METAL combines Mizuno’s powerful HotMetal™ single-wall aluminum alloy with innovative CorTech™ technology, which adjusts wall thickness across the barrel to create a high-performance bat with an aggressive sweet spot. Engineered details like an Optimized End Cap create a booming sound, while also increasing the size of the sweet spot to give you the ultimate one-piece bat.

- CORTECH™: Generates a wider sweet spot and reduced MOI for more power, forgiveness, and a faster swing speed for better performance at the plate.

- Hot Metal™ Alloy: A stronger alloy that allows for thinner walls, which leads to more pop and distance, without sacrificing durability.

- One-Piece Construction: For maximum mobility and comfort.

- Optimized End Cap: Great sound on batted balls, while also positively affecting the bat's sweet spot to give you more pop.

- USSSA Approved.

- One Year Warranty.
